Why is my dryer running but not heating?
A dryer that tumbles without heat has usually lost its heating element or tripped a thermal fuse. Thermal fuses do not fail randomly — they blow because airflow was restricted, so replacing the fuse without clearing the vent means you will be calling us again shortly.
Likely causes
- Thermal fuse blown, almost always caused by a blocked vent
- Heating element burned through
- Cycling thermostat or high-limit thermostat failed
- Only one of the two 120V legs reaching the dryer — a breaker issue, not a dryer fault
- Control board no longer calling for heat
What we do
We check the supply voltage first, because a half-tripped double breaker mimics a dead element exactly and costs you nothing to fix. Then we test the element, thermostats and fuse — and we clear the vent, because a fuse that blew once will blow again if the airflow is still restricted.
What affects the cost
Fuses and thermostats are inexpensive; elements are mid-range. Vent cleaning is included as part of the diagnosis rather than billed as an extra.
